From e13cf03eaae3792442c401860910d40f33c89a33 Mon Sep 17 00:00:00 2001 From: Ben Dooks Date: Thu, 30 Jul 2009 23:23:35 +0100 Subject: ARM: S3C: Update CPU register mapping practices. Currently map-base.h defines the main virtual address mappings made for all the support S3C SoC series, but does not then define any base for per-cpu mappings to be made from. Add S3C_ADDR_CPU() macro to define an virtual address as an offset from the last of the core mappings.
